To all whom 'it may conce'rfr'i:l Be it known that I, JOSEPH MCDERMOTT, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented. a new and usefulConveyer and Leer-Charging Mechanism, of which the following is a specification. v

This invention relates to a device for handlin articles.

T is invention has-utility when adapted to transporting glassware, particularly in pre1 paring glass articles for and charging them' into leers.

Referring to the drawings: Figure 1 is an illustration of an embodiment of the invention for receiving bottles, as from a bottlemaking machine, for ,fire finishing the stopper opening and transporting the bottles into a leer, parts being broken away; Fig. 2 is a fra mentary plan view in section, on a larger sca e; Fig. 3 is a section on the lineIII-l-III, Fig. 2; Fig. 4 is a detail disclosing a portion of a mechanism whereby a second or follower transporting device section may be driven, or caused to have a determined rate of travel relative to the transporting device delivering thereto; Fig. 5 isa section on the line V--V,

v4, looking in the direction of the arrow; Fig. 6 is a plan view of a )ortion of the transporting device having a 're finishing section in the form of a shunt or by-pass; Fig. 7 is an elevation of the fire finisher as shown by a longitudinal section through the trans orting device with the spiral removed; an Fig. 8 is a view similar to Fig. 6 with the fire finishing bypass eliminated. Y

rIllustrative of a form of driving mechanism is here shown the belt 1 for actuating the rotatable article impelling or transporting or transporting device as bottles 3, delivered by chute 4, as from a bottle making machine. l cated in a box or housing 5, having slots 6 in the bottom thereof., and sectional cover 7.

The slots 6 permit of some ventilationwithout allowing cold drafts to directlystrike the warm glassware, while the slots also mini-l mize the friction surface at the trou h -botend.

travel of the article, by offering less surface for contact. This transporting deviceand housing for the way are supported by uprights 8.

That end of s iral 2 remote froindriving belt 1 is provide with gear 9 having teeth of such bevel that the spiral section 2 may be placed at the desired angularity to the succeeding follower section. Meshin with gear 9 is gear 1() of equal size, in order t at the determined rate of travel of the follower sec-v tion may be in this instance the same. as that ofthe section 2. This gearl() is moiinted'on large bearings 11, and has a segmental web orv thus providing the c arging device with norelatively moving parts exposed to the heat of the leer. The spiral 14 in extending across the leer 16 is located just above'the endless platform or leer pans 18, which are movable to convey the articles annealed through the leer from the charging end to the discharging The terriperature of the leer is conof su plying gas for fuel which is burned at thefliiejoutzlets in the leer.

When-the impeller or spiral 14 causes a bot tle to be forced against the stem 2() extending into the leer, this stem is forced outward against the resistance of spring 21, causing a contact to be made 'between lines 22 and 23, to thereby close a circuit and bring about the movement of the leer pans through signalingattendant by ringing hell 24. As show-n in Fig. 5, there is an opening 25 between. the housing for spiral sec-tion 13 and spiral section. 14 to ermit `rotation of the web 12.

In hand ing-some classes of glassware' articles, for instance, fruit jars, there is not the necessity for iire finishing the stopper or closure en d thereof, under which circumstances the', ,leer charger in the form thus far described 'answers sion 26, disclosed with rollers therein to minimize friction. Hinged to housing side 5 are sections 27 28, which when moved out ot' line of side 5 may form two sides of platform 26, the third side 29 being lixcd. Then this platform 26 is thus housed it forms a shunt or by-pass fire-finishing section providedwith sets of burners 30. Pivoted to side section 28 is bell .crank lever 31, which by working through a slot in side 29, may throw side 28 into line with side 5. For operation, the bell'crank lever 31 is mounted onbracket 32, the lever being engaged by link 33 extending to hand lever 34 having segment and detent.- Operation: It is desirable that the relative speeds of the transporting devices be determined in order to avoid congesting. Herein the successive devices rotate at the same speed, gears- 9,'10, being equal, and the source of power from, belt 1 causes .spiral 14 to beA driven through spiral 2.. Bottles 3, entering the chute 4, say as discharged from a bottle making machine, are

deliwered to one side of the spiral 2, which so rotates as to coact near theA bottom with the bottle and urge it along the slotted wayin the housing 5, which action while moving the bottle forward causes it to hug the outer wall of the way housing. Accordingly for those articles .which it is desired to hre finish, with' the by-pass opened out, the bottles 3 will at once be directed thereinto, and as succeeding bottles come along, the preceding ones are eachr urgedr forward one space,'thus intermittently mov- '.ing from burner to burner 30 of the rire i travel. `The end walls 27, 29 of the by-l 'finisher and then getting back. Ainto the transporting device .for continuationl of pass are inclined, so that the articles entering and' leaving may be' readily urged along. The entering bottle as it starts away from spiral 2 and along wall 27, is engaged farther from the bottom by the spiral and the line of contact with the bottle is more directly working to push the bottle away than vto urge it forward, so the bottle readily moves under a burner, which action has moved the bottle from the last burner out suili'- ciently far to be engaged by spiral 2 and conducted onward. lThen a batch is completed, f to empty the ire nisher, hand lever 34 is radually moved, so that the articles in the re finisher are successively taken up by the spiral 2. ln closing the vlireinisher, the burners 30 must be iirst swung upward as shownin Fig.. 8, so that wall 28 may be placed in position. With the finisher so closed, articles n ot to be ire-iinished'may be regularly run through. The lateral urging of the articles hel s in delivering them to the succeeding spira 13, which coacts with the articles in a similar manner to continue thearticle travel. In Fig. 2 there is a ledge 5,V extending in line with way 5, Iso that the bottles 3 are kept Within actuating range of spiral 2 until spiral'13 may engage, when through the combined action of the spirals and incline 15 the articlesare directed into the housing 15'to be transported by spiral 14'. The web 12 of gear 10 isl designed to leave ample opening for travel of articles therethrough, and still be strong enou h to support and drive spiral' 13, 14. T e narrow opening 25 in no wise interferes with lthe onward movement of the bottle toward the leer. The tendency'of the articles to get away from the impellers, causes the first articles reaching the leer to be deposited on ans adjacent the entry' or charging opening, the succeeding articles only being kept in impelling relation with the spiral 14 by the articles already in theleer. Thus a grouping of the articles is gradually ex tended across the leer, and when an article is caused to actuate the plunger 20, the

signal isautomatically given by electric bell 24 for shifting the pans 18 forward, if this shifting is to vbe manually controlled, instead of having the device perform this operation directly. As the pans move forward, the spring 21 forces the stem 20 inward, when the articles are out of the way, the alarm ceasing, and the continuous operation of the transporting device is in no wiseinterfered with,- the charging proceeding being repeated as above described. This mechanism is especially advantageous in permitting operation to be uninterrupted. For instance, the hot bottles from the bottle making machine, at once received in the inclosed -way, have not opportunity to cool materially, may be ire-iinished economically without any handling whatever by labor,as they are ladvanced at the desired rate/of travel intothe leer continuously. No intermittent stopping, wasting of heat by cooling o f articles.

and leer is avoided, advantages in themselves, but all working together in theV structure herein disclosed to 'make possible a maximum of output at a minimum of cost.

The arrows, Fig. 2, indicate the direction of rotation bf spirals, that the travel of articles may be as described when the pitches as shown are used. -The articles are individually impelled and delivered to the succeeding section forlike handling. Furthermore, the articles are handled in an Vorderly manner, always in a determinedv osition as to the spiral-on one side thereof? It will be particularly noted that, in my improved construction, there lare no relatively moving parts in contact with each other exposed to the heat of the leer, or to rapidly varying temperature conditions, as in the case of endless conveyers. porting device is'mounted in bearin s Wholly external of the leer, and hence'lu rication may be readily maintained. Moreover, all parts of the` mechanism are subjected con- ,stantly to substantially -the same tempera- Mportion, and a way adjacent, the impelling' 1z The combination with a leer, of a rotary .device having an axial terminus exterior of the leer, said device embodying an iinpelling portion and along which the impelling portion is effective to cause the travel of objects l fing means for impelling the ware transinto the leer.
